VENTIETH TO M. H. DUCKETT,

VENDING EEACHINE.

This invention relates to vending machines and has special reference toa vending machine principally for use in vending newspapers although thesame may be used to vend magazines, pamphlets. and the like by minormocitications of the coin receiving apparatus.

One important object of the invention is to improve the generalconstruction of devices A fourth important object of the invention is toprovide an improved coin receiving apparatus for use in connection withsuch a machine. r

A fifth important obiect of the invention is to provide a novel coinreceiving apparatus which may be adjusted to operate with either asingle coin or a number of coins in accordance with the price to beobtained for the article sold.

With the above and other objects in view as will be hereinafter apparentthe invention consists in general of certain novel details ofconstruction and combinations ofparts hereinafter fully described,illustrated in the accompanying drawings and specifically claimed. r y

In the accompanying drawings like characters of'reference indicate likeparts in the several views, and:

In the construction of the invention as here disclosed there is provideda casing having a bottom 10 a front wall 11 and side walls 12. Thiscasing also has a rounded top 13 so that rain will run off from the top.The rear wall of the casing is provided with a door 14, the door beingprovided vith a suitable lock 15 to prevent improper access byunauthorized persons. said door being of ordinary construction andarranged to swing open to affordaccess to the interior. Fixed to thefront and rear walls of the casing adjacent but in spaced relation withthe side walls are vertical rack bars 16 and within the casing'is anelevator or carrier 17 having a series of inclined plates 18 extendingfrom itsfrontto its rear and provided with suitable small anti-frictionrollers 19 so that newspapers or pamphlets placed on these plates fromthe rear when the door is open to the slides, will roll down toward thefront. I is to be understood that this elevator is open at the front andrear the side walls being tied together below by certain shafts. Gn thefront shaft 19 and rear shaft 20 are revolubly mounted gears 21 jacentthe top of the casing is a cross bar 27. To this cross bar is'fixed oneend of a pair '-of sprocket chains 28 each of which extends downwardlyfrom the cross bar around and beneath'the sprocket 26 and then upwardlyand over a'sprocket 29carried on a shaft 30 extending across the upperpart of the casin s From the sprocket 29 the chain runs rearwardly andpasses over a sprocket31 carried ona shaft 32 and then downwardly in asuitable guide pocket between the respective rear rack bar 16 and theside wall of the casing, the

downwardlyextending portion of the chain carrying a weight 33 which iscapable of adjustment by'means ofadditional weights 34. At the front ofthe casing the wall 11 is provided with a delivery opening 35 and to thebottom edge of this opening is hinged a door j 36 which tends tosp'ringslightly open through the action of a spring 37 which only actsdur- L v ng the first part of the movement of the door 36, the'door whenthus sprung open engaging a heavier spring 38 which acts at this time asp a stop. Adjacent-the chain 28 is a guide '39 which prevents thlschainfrom mov ng lat erally and pivoted to each side wall ustin front oftherespective chain is a bell crank lever 40 having onesubstantiallyhorizontal arm which carries a trip pawl 41 normally extendmg through the cha m and through a slot 42 in the guide 39 andnormally held in aline- "ment with the horizontal arm of the lever 40 bya spring 43. The lever 40 also has arsubstantially vertical dependingarm which is 38 the lever 40 is rockedand the dog or pawl 41 will slidedown into the next link of the chain 28 and its end will slipthroughthat linln 'Now, the door 36 is pulled open against the sp 'ing38 but when the door is released the spring 38 is sufliciently strong-tosnapthis door shut and at the same time operate the link and lever to rase the chain 28. It s to be understood that the carrier is wellcounterbalanced so that not much effort is required to: liftit. As thispart of the chain 28 moves upwardly it causes rotation of the sprocket26 which, through the-gears 24 and 23; actuate the gears 21 to rollupwardly on the racks -16and thus lift the carrier. In this manner 1every time} the door is :closed the carrier raisesa distance equal tothe distance between adjacent plates 18 so that when the door is openedand a paper withdrawn the release of 'the'door closes said door andplaces a I second paper in position for withdrawal. In

order to prevent rattling of the carrier idler gears or rollers 46 maybe employed at the top.

- When the carrier is fully loaded the counter- 1 weights 33'and 34maybe assisted by coiled compression springs 47 at the start of the lift"mg, these springs, of course losing their.

lifting efiect as they expand which is desirable since the removal ofthe papers one by one gradually lightens the weight of thecarrier andits contents. backward movement of the carrier there is fixed on theshafts 19 and 20 the arms 48 carrying spring pressed dogs 49 whichengage the rack bars 16 and which maybe released from the rear of themachine by manipulating the wires 50 for the front dogs and the crossbar5l for the rear dogs. 7

vThe door 36 in its closed position inclines upwardly and has a verticallip 52 which carries a keeper 53 engagedby a latch end 54 formed on'acertain lever connected with the coin operated mechanism. The lipclosesagainst an inclined cover portion 55 having a transparent window56 through which may be observed the condition of the carrier-so as toshow whether or not there are papers therein Above thedoor is a casing57'carrying a' name plate or instruction plate 58 and over these partsand'the coin mechanism-is arranged a hood59. V

The coin mechanism is located in a casing "60 mounted'on the side ofthemain casing and projecting somewhat in front of the front plate 11.This casing 60 has a door 61 provided with the usual lock 62 so thataccess can be had thereto'by proper persons for the removal of ihecoins. Extending through the front wall; of thecasing 60 is a guideplate 63 having inturned edges 64 and on this guide'plate, between theinturned portion, slides a coin slide 65 having uprturnedends 66 to forma finger grip. This coin slide has intermediate its ends a coinreceiving slot oropenlng 67 which, when the coin slide is pulledoutwardly, is exposed so that a coinmay be placed thereon. The latch.54, ;ipreviously referred to; is on the end of a'bent lever 68 whichextends'h erally' through a suitable opening in the 51GB wall 12 of themain casing and then rearwardly so that'it may be'pivotedadjacent itsrear end to a fulcrunrbracket 69 fixed in the when a, coin isplaced inthe coin slot and the 7 Slide pushed in the coin will engage and do Inorder to prevent press the rear end 70 and th'erebyraise-the latch 54out offthe keeper 5 3 a coverplatc' -71holding the coin downward topermit this such coinbeing'shown at C.

Secured to the front wall of the casing 60 is aspring stop72 whichpermits the coin to passrearwardly but catches the same-and prevents itsbeing again pullel out. Asprin 73 urges the forward end. of the lever 68downwardly but yields readily to the action of thecoin.

If it is desired to-"use the invention for papers of different value aslight modification of the lever 68 and slide 65 may be made as shown inFigure 18. In this modification the opening 67 is made sufficientlylarge to receive several coins C and inplace the upturned end 70 thereis provided a sliding arm 7O secured in adjusted position on the rearend of the lever by a set screw 70'. Thus, it the paper is to cost threecents, three coins mustbe placedin the coin slide since if only two areplaced therein the arm 70 which has been adjusted for three, will not bereached when the slide is pushed fully in and therefore the latch 5awill not be released. Obviously, if the paper is to cost two cents orone cent the arm 70 lSlIlOVQil to appropriate position to engage therear coin of the two or the single coin. In general the device. isoperated by drawing out the slide and placing the proper coin or coinsin position. The slide is then pushed in whereupon the latch 5 releasesfrom the keeper 53 and the door 36 springs slightly open. The purchaserthen depresses the door, withdraws the paper which has slid down readyto be grasped and releases the door which then springs up and closesready for the next purchaser.

There has thus been provided simple and eflicient device of the kinddescribed and for the purpose specified. g

It is obvious that minor changes may be made in the form andconstruction of the invention without departing from the material spiritthereof It is not, therefore, desired to confine the invention to theexact 7 form herein shown and described, but it is desired to includeall such as properly come within the scope claimed.
